Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537258, here are decompositions:

19 + 33537239 = 33537258
31 + 33537227 = 33537258
59 + 33537199 = 33537258
67 + 33537191 = 33537258
71 + 33537187 = 33537258
137 + 33537121 = 33537258
197 + 33537061 = 33537258
211 + 33537047 = 33537258

Showing the first eight; more decompositions exist.
